registerSingletonWithDependencies<T extends Object> method

void registerSingletonWithDependencies<T extends Object>(
  1. FactoryFunc<T> factoryFunc, {
  2. String? instanceName,
  3. Iterable<Type>? dependsOn,
  4. bool? signalsReady,
  5. DisposingFunc<T>? dispose,
  6. Set<String>? registerFor,
})

registers a type as Singleton by passing an factory function of that type that will be called on each call of get on that type T type to register instanceName if you provide a value here your instance gets registered with that name instead of a type. This should only be necessary if you need to register more than one instance of one type. Its highly not recommended dependsOn if this instance depends on other registered Singletons before it can be initilaized you can either orchestrate this manually using isReady() or pass a list of the types that the instance depends on here. factoryFunc won't get executed till this types are ready. func is called If signalsReady is set to true it means that the future you can get from allReady() cannot complete until this this instance was signalled ready by calling signalsReady(instance).

Implementation

void registerSingletonWithDependencies<T extends Object>(
  FactoryFunc<T> factoryFunc, {
  String? instanceName,
  Iterable<Type>? dependsOn,
  bool? signalsReady,
  DisposingFunc<T>? dispose,
  Set<String>? registerFor,
}) {
  if (_canRegister(registerFor)) {
    locator.registerSingletonWithDependencies<T>(
      factoryFunc,
      instanceName: instanceName,
      dependsOn: dependsOn,
      signalsReady: signalsReady,
      dispose: dispose,
    );
  }
